Fuel pump
« on: Jun 28, 2013, 12:20:42 am »
Thought I might start a thread for the fuel pump itself. Ares posted in his thread the first time he had it replace. He mentioned these characteristics below which I am now experiencing

Here are some symptoms to watch for that could be the fuel pump:

    Trouble starting that continually gets worse over time
* I don't have any issues starting the bike
    Engine feels like it cuts out while riding
* I haven't had it feel like it will cut out
    Engine idle dropping when sitting still with clutch in or engine actually dying
* I have had this happen a few times - seems to happen on long rides
    When giving full throttle the bike does not respond immediately
* I have noticed this just today ..
    When cruising and suddenly cranking on the throttle you hear a bizarre ass noise
* I don't think I want to hear this noise
    Your gas mileage seems to increase for no reason
* gas mileage is still as expected
    Will most likely experience more decel popping/backfires
* haven't noticed any more than normal backfires

I think I may call and see how much a fuel pressor test would be. I might also try some seafoam and will try not to let the light come on anymore - I've done it a few times.

    Great idea Dreadly but I am hoping I will never have to come back to this thread for my own verification...  :o

    Admin, maybe this thread can get a sticky...  :shrug:

      After my recent experience, I can only agree.
      To live on two wheels is to live a life in balance!

      Great. I'm starting to experience a couple of those symptoms and was afraid it might be the pump going.

      What kind of mileage are we talking when symptoms start?

      I believe:
      Ares - 35k
      Woodog - 31k
      Wolfraider - 87k
      Kewlraider - don't recall
      v8_vega - don't recall
      seventhLetter - don't recall
      wileecoyote - Roadstar - 26k

      I'm currently at 25k ... nothing has failed yet but ...................

      I went ahead and stickied this thread. 

      The thing with the symptoms is that many other things can cause the same symptoms.  Each time it happened to me, I first did the Seafoam.  It would help for a day or two and then get worse. Then I'd chang plugs and clean the air filter. Again, it got better for a couple of days and then got worse.  I think Wolf and Woodog experienced similar things.  Eventually after it had already been diagnosed the second time, there were times I'd be riding along and you'd feel the engine cut out for a second.  It was usually in the afternoons. Which means it was because it was running hotter or because it was lower on fuel, since I have a full tank in the morning.   I believe Wolf experienced the loss in acceleration as well.  Correct me if I'm wrong.

      On a ride Saturday, the bike stalled after going through two tanks of gas along with 1/2 seafoam.

      Are you feeling any cutting out when riding? Like a loss in HP for a moment.

      Not sure what whine you're referring to. Are you saying when you turn the key on or start the engine?

      Once or twice ... but it's done that for a few years.

      Really?  Only time I ever had that happen was when the fuel pump was going out.  Have you checked the plugs and air filter? Both will cause the same symptoms.

      Could check the plugs ... air filter is new this year.
